Virasoro conformal blocks are expected to exponentiate in the limit of large central charge c and large operator dimensions h i , with the ratios h i /c held fixed. We prove this by employing the oscillator formulation of the Virasoro algebra and its representations. The techniques developed are then used to provide new derivations of some standard results on conformal blocks.

半经典 Virasoro 块：求幂证明

预计 Virasoro 共形块在大中心电荷 c 和大算子维度 hi 的限制下取指数，而 hi /c 的比率保持固定。我们通过使用 Virasoro 代数及其表示的振荡器公式来证明这一点。然后使用开发的技术来提供保形块上一些标准结果的新推导。
